I often get into a situation where I can't type anything in Colloquy windows. I am not sure how exactly to reproduce it, but here is something that seems to mostly work:
- Type something (in some channel, not in the server console or other windows)
- Hit Cmd-A (for Select All)
- Hit Option-Delete (Backspace) [maybe Cmd-Delete also works here?]
- Hit Cmd-Z (for Undo)
Now, if everything goes (not) well, you can't type anything at all in any of the chat windows or the server console. You *can* paste from other windows. You *cannot* hit Return to send the pasted message. You *can* hit Cmd-J (for example) and type channel names in the window that pops up. You just can't type in any chat windows.
Minimising and restoring Colloquy does not help; the only way out is to restart Colloquy.
